Description
BACKGROUND OF THE INVENTION
[0001] The present invention relates to a scanner and more
particularly pertains to a handheld portable scanner with
integrated technologies which effectively combines lighting,
electronics and mechanical technologies and has a small size and
convenient portability.
[0002] Currently, scanners in the market are of sheetfed type which
scans the documents directly to computers. Scanning documents are
greatly limited by the space available. The present invention is
not of sheetfed type and can be directly dragged across the
scanning documents; the user may adjust the scanning speed by
himself, making the operation very convenient. The scanned
documents would be directly saved to the internal storage device in
the invention or the expansion card. The operation of scanning
would neither be limited by the venue nor space.
BRIEF SUMMARY OF THE INVENTION
[0003] In view of the aforesaid disadvantages now present in the
prior art, the present invention provides a handheld portable
scanner.
[0004] To attain this, the present invention generally comprises
the following:
[0005] A handheld portable scanner which comprises a scanner
housing, a battery, scanning components and image processing
components. The scanning components are composed of an optical
scanning head and a scanning rod. The image processing components
are composed of scan-speed testing components which are coupled
with the scanning rod, a processing chip for processing of data
scanned by the optical scanning head and image processing, and a
scanner circuit.
[0006] The scan-speed testing components are composed of a gear set
and a light sensor connected to the gear set. The gear set is
driven by rotation of the scanning rod while scanning. The light
sensor converts rotation speed of teeth of the gear set into a
speed signal, which is transmitted to the processing chip of the
scanner for processing.
[0007] Rubber rollers are disposed on the scanning rod to increase
friction and guarantee dragging direction and stability while
scanning.
[0008] The scanner has an internal storage device or is disposed
with a slot for expansion storage devices. The user can save the
scanned data to the expansion card received in the slot for
expansion storage devices or the internal storage device depending
on actual need. The internal storage device can co-exist with the
slot for expansion storage devices.
[0009] The scanner is further disposed with slots for data wires,
through which the transmission of data to computers can be
realized.
[0010] The scanner housing is further disposed with an LCD screen,
LED indication lights and scanner control keys.
[0011] The present invention provides a handheld portable scanner
which has a convenient portability and extensive functions. More
importantly, with the coordination of the speed testing components
and the processing chip, the present invention can correct scanning
errors caused by uneven speed of manual scanning by means of
computation of the chip, thereby ensuring that the scanning output
is the same as the original document. To ensure the quality of the
scanned document, reminder function is also available in case the
dragging speed of the scanner is too fast. The present invention
also significantly increases the efficiency of scanning by changing
sheetfed scanning into direct scanning. The handheld portable
scanner of the present invention integrally realizes functions such
as scanning of images and text, data processing and storage as well
as output of images to the computer, which significantly saves the
user's time and offers convenience and reliability. The present
invention can also realize unlimited scanning capacity by choosing
storage cards of different storage capacities (or by backing up
multiple storage cards). The present handheld portable scanner
saves the data of the scanning document to the internal storage
device or expansion cards in digital image file format such as
JPEG, TIF and so forth for direct retrieval. Scan page count and
display function as well as low power reminder function are also
provided.

DETAILED DESCRIPTION OF THE INVENTION
[0016] Below is a further illustration of the present invention
with reference to FIG. 1 and FIG. 2 which allows a person skilled
in the art to comprehend and realize the concept of the present
invention more easily.
[0017] A handheld portable scanner comprises a scanner housing,
wherein an optical scanning head 7 is disposed on one side thereof.
A scanning rod 4 is disposed next to the optical head 7 which is
coupled with the optical scanning head 7 while scanning.
[0018] As illustrated in FIG. 3, the scanning rod 4 rotates on its
own axis. Rubber rollers 5 are disposed on the rod in order to
increase friction while scanning and also to guarantee the scanning
direction.
[0019] The scanning rod 4 can also drive the scan-speed testing
components through its rotation. The scan-speed testing components
comprise a gear set 2 and a light sensor 3 for the detection of the
gear set. The gear set 2 comprises a transmission gear set and a
speed testing gear. Through the rotation of the scanning rod, the
transmission gear set drives the speed testing gear, whose teeth
are disposed in the light sensor 3 on the scanner circuit.
[0020] When the speed testing gear rotates, the light sensor 3 can
sense the rotation of its teeth and thus calculates the dragging
speed of the scanner. The light sensor transmits the obtained data
to a processing chip (CPU) 1 for processing of data scanned by the
optical scanning head and image processing. The CPU1 determines the
dragging speed of the scanner and automatically adjusts the number
of scanning lines to maintain the scale and quality of the scanned
images.
[0021] The CPU1 of the scanner also processes the images scanned by
the optical scanning head and transmits them to a storage device of
the scanner after integrated processing.
[0022] The storage device of the scanner may comprise an internal
storage device 6 and an expansion storage card, with the internal
storage device 6 disposed on a PCBA and the expansion storage card
connected to a card slot on the PCBA.
[0023] The handheld portable scanner is further disposed with slots
for data wires. Through the data wires, the scanned images can be
easily transmitted to the computer for use.
[0024] As illustrated in FIG. 4, control keys and LED indication
lights are disposed on the housing of the scanner. The LED
indication lights are red and green in color respectively when
turned on. When a POWER key is pressed to activate the scanner, and
the Scan key is pressed (the green LED light is on), the user may
drag the optical scanning head across the scanning document. When
the red LED light is on, it reminds the user to slow down the
dragging speed of the optical scanning head 7. When the red LED
light flashes, it reminds the user that the current dragging speed
of the optical head 7 is too quick; if the user does not slow down
the speed, the documents obtained through scanning by the optical
scanning head 7 would be deformed. Thereafter, the scanned document
would be saved to the memory card.
[0025] The above is a detailed description of a handheld portable
scanner provided by the present invention. The embodiments employed
herein are for illustrating the structure of the present invention.
The above embodiments are only for the purpose of comprehending the
key concepts of the present invention; Also, modifications may be
made by a person skilled in the art to the manner of operation and
the scope of application according to the spirit of the present
invention. In view of the above, the foregoing should not be
regarded as limiting for the present invention.
